I am looking at purchasing either a truck mounted dump or possibly a trailer mounted dump before the next construction season. I see Smithco http://www.sidedump.com/ has both truck or trailer mounted side dump trailers. Trailking makes a nice looking 30 yard end dump trailer http://www.trailking.com/trailers/index.php?id=20 and Bomax makes some nice looking truck mounted end dumps http://www.bomax.com/. I clear a lot of land and would like a dump that will not hang up stumps or logs while dumping. The Sidedump looks perfect for this, and an end dump with the high lift tailgate shouldn't have too much problem either. I am looking at the half round end dump beds with 1/4" AR400 steel because I may also haul rip-rap, tailing, gravel, concrete demo, etc... One driver I talked to stated that many of the trucks pulling Sidedump trailers were twisting their frames because of the sideways forces exerted on the truck while dumping. He also stated that this could be damped somewhat by releasing any air out of over the axle air bags to resist some of these forces on the tractor. He also stated that the Sidedumps are a little less versatile dumping material because if the side placement. I'd like to hear others thoughts on the side dump vs. the end dump. Thanks.
